Hello everyone,
Two months ago, we purchased a serviced building plot on a hillside and are currently deeply involved in the floor plan design, which is proving quite challenging due to the elevation difference.
I have been following the forum for a while and recently found a great template for our project that I think just needs some adjustments to fit our requirements. I would really appreciate your feedback and am, of course, open to criticism!

If you have to give up something, which details or features
Why does the design look the way it does?
We really like the design here by "kaho674." It truly reflects our ideas. The upper floor should still fit now but, of course, with our minimum required room sizes and the requirement to build only 1.5 storeys.
What is really important to us, especially since the plot is on a slope — the highest point at the street is just under 1m (3.3 ft) above the zero level and it drops 5.11m (16.8 ft) to the lowest point — is how everything can be integrated into the plot without the costs for filling and leveling running out of control. We have also considered an alternative to the urban villa in the style of a split-level house. What have your experiences been building on such a plot?
Many thanks

They are not. I had written that as well. Still, 220 sqm (2,370 sq ft) for 450,000 is more realistic than 140 sqm (1,505 sq ft) for 250,000.
There are many costs that occur regardless of size or do not increase linearly. You cannot say house costs: 140 x 220 = price of a large house.

You have many costs that are fixed regardless of size or do not increase linearly. You can’t just say house cost: 140 x 220 = price of bigger house. I am aware of that, but then a figure of 400k plus X doesn’t fit my situation. The starting point is very similar, and the other is a significantly larger house. Also, all the spaces need to be finished with quality materials.

All the areas also need to be finished to a high standard. Don’t worry about it. He won’t get very far with his 450,000 euros. Just the balcony with thermal separation of the base slab costs 6,000 euros net for a 6 x 3 m (20 x 10 ft) area without the columns. Double that plus columns, railing, drainage, flooring, etc. That measure alone costs 30,000 euros. Then 220 m² (2,368 ft²) of living space at quality level comes to 440,000 euros. Add incidental construction costs and suddenly you’re looking at a figure well into the 500,000 euros range.
Your 400,000 euros completely covers everything (including a brick veneer facade) except the kitchen; only the garden and fence need to be done, and if you’re careful, the kitchen might even be included.
...I had also planned to expose the basement and build an elevated terrace on the ground floor. Unfortunately, I had to abandon this idea. Even though it would have eliminated the need for retaining walls and backfilling, I would have had to remove and dispose of about 900m² (9700 sq ft) of loose soil. For soil class Z0, I had a quote of €23,000. The terrace alone would have cost an additional €30,000. On top of that, the basement side would need extra plastering, and a staircase down to the garden. Still, retaining walls to support the carport would cost around €10,000, and so on.
However, since the soil analysis showed soil class Z1.1, the excavation and disposal costs would have tripled. That ruined the idea completely.
This clearly shows how important a soil analysis is. If the analysis is only done at the disposal site, you’ve basically already lost in a situation like this.
